T0 all whom/t may concern.'

Be it known vthat I, OTTO Lwnnnnnm subject of the` German Emperor, residing at Cologne, Germany, have invented new and useful TmprovementsA in Cable-Lubricators; and I do hereby declare the `following to be a full, clear, and exact description of the same. a

This invention relates to a lubricating device for the carrying cables oi' cable railways,

in'which al forcing lpump is arranged at,y the bottom in the oil tank andforces the oil to a point abovethe 'carrying cable.,A Lu- Y bricating devices of this kind are already well known, but the present invention isV a great simplification compared to the well known devices, as: regards the transmission of movement from the running gearto the pump. The movement is transmitted by a straight spindle which iscarried through the suspension journals of the car suspension. The spindle is rotated by means of a bevel wheel gear which is arrangedin such manner that the aXle of thedriving wheel coincides with the `suspension journal, so

that in casey of oscillations of the suspen-v sion relatively to the running gear, the

proper en ga gement of the bevel wheel pair is not disturbed.

A construction according to this invention is illustrated by way of example in the accompanying drawing in which- Figure 1 shows the running gear with a portion of the suspension in side elevation; Fig. 2 is a section in the center through the running gear and Fig. 3 shows the bottom portion of the suspension with the oil tank. Fig. 4 is a side elevation of the suspension as a whole.

The running gear consists ofthe running gear frame 1 and the running rollers 2 and 3 mounted in the same. Between these two rollers in the frame, 1, is mounted a bolt 4V on the laterally projecting portion of which rests the suspension 5. On the suspension is mounted a box 7 formed into an oil tank and containing the rotaryy pump. 8. The pump in question is driven by the spindle 9, passing centrally through the bolt 4 and carrying at the upper end a bevel wheel 10.

The latter is Yin engagement with a bevel wheel 11 arranged concentrically with the bolt 4 and carrying an outer toothed rim 12. This toothed rim is in engagement with the toothed wheel 13 secured to the running wheel or roller 3. The spindle 9 is surrounded, on

the section from the oil tank to the suspension head,'by a. tube 14, which is so wide that an annular space is left between the spindle and the tube for conveying the oil upward.

Thesaid annular chamber is adjoined atl the mounted the pump 8, is connected by means of an overflow pipe 19 to the other portion of the oil tank. Y A valve 20 enables the crosssection of the overflow to be modified, and in'zthat way, the quantity of the oil which is forced upward in the tube 14, to be regulated. This regulation could of course also be effected by other auxiliary means.

The device is not limited to the usey of a rotary pump but can be worked by means of any desired kind of pump'. The essential point for obtaining the object of the invention is merely the arrangement of the driw ing spindle,f-and the transmission ot' motion from the running wheel to the said driving spindle.

Having :fully described my invention,

what I claim and desire to secure by Letters Patent is 1. In a cable lubricator, the combination of, a running gear trame; rollers therein; a

bolt on the frame; a suspension on said bolt;

a tank and a pump therefor on said suspension; a spindle connecting with the pump and passingv through said bolt; a gear wheel on said spindle; and a gear co-axial with said bolt and adapted to ltransmit motion from one of said rollers to said gear wheel.

2. Tn a cable lubricator, the-combination of, a running gear frame; rollers therein; a bolt passing through the frame; a suspen ysion on said bolt; a tank on the suspension; a pump communicating with the tank; a spindle connected to Vthe pump and passing through said bolt; a gear wheel on said spindle; and a gear co-aXialwith said bolt and adapted to transmit motionfrom one of the rollers to said gear wheel.

3. In a cable lubricator, the combination of, a running gear frame; rollers therein; a bolt passing transversely through the frame and provided with an oil conveying bore; a wheel on said bolt and adapted to be rotated munieating with the tank; an operative connection"betweenthe pump and said vvheel;
